Adverse effect of electrolytic/caloric/wtr-bal agnt, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to medications that affect electrolytes, fluid balance, or caloric intake. These sequelae are persistent health problems that arose directly from the initial adverse drug event.

This code is appropriate when a patient presents with a chronic or permanent condition that is a direct consequence of a previous adverse effect from drugs like diuretics, antidiuretics, or nutritional supplements. Examples include chronic kidney disease following acute kidney injury from a diuretic, or persistent electrolyte imbalances after a severe adverse reaction to an electrolyte-altering agent.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current sequela to a past adverse effect of an electrolytic, caloric, or water-balance agent.
• Do not use this code for acute adverse effects; it is strictly for residual conditions.
